I suppose it depends on where you live. I prefer tiny cars, because I can park them nearly anywhere. I can fit into tiny NYC spaces that others have to pass. And since my only regular back seat passenger is a six-year-old, if the back seat is a bit small, no biggie. Although it's a Honda Civic, and the interior, for a small car, is actually quite roomy - I've put a 6'4" man in the back seat, and he came out alive. In addition, I'm short, and a small car actually fits me better. As for cleanliness - again, I mention the six-year-old; but relative to most other cars with six year old children in them, mine is quite clean. Again, relative.
